Regression results on the testing set compared to the ground truth IC50 values. The x axis is the experimental IC50 in natural logarithmic scale, and the y axis is the predicted IC50 in natural logarithmic scale. Different colors demonstrate how many testing samples fall in each small square of 0.1×0.1, or the hot map of the distribution, where dark purple indicates more samples (around 30 samples per small square 0.1×0.1) and light blue indicates fewer samples (less than 5 samples per small square 0.1×0.1)
